A culvert end for a culvert includes a culvert body and a brow. The culvert body has an upper section and an outer end that defines an opening. One or more structural weaknesses are formed in the culvert body. The one or more structural weaknesses are configured and arranged to encourage a partial collapse of the upper section of the culvert body when the culvert end is subjected to a sudden end-on force caused by a vehicle impacting against the outer end of the culvert body, thereby creating a transitioning surface that enables the impacting vehicle to ride over the outer end of the culvert body. The brow is formed at the outer end of the culvert body and configured to initiate the partial collapse of the upper section when the brow is struck by the impacting vehicle.
